Analog Devices Inc./Maxim Integrated MAX1833EVKIT

Overview

MAX1833EVKIT from Maxim Integrated is a fully assembled and tested evaluation kit for the MAX1833 high-efficiency, step-up DC-DC converter. It accepts 1.5V–3.3V input, delivers regulated 3.3V at up to 150mA, features synchronous rectification, reverse-battery protection, and 1µA shutdown current-optimized for portable hand-held devices requiring extended battery life.

For engineers reviewing the MAX1833EVKIT datasheet, MAX1833EVKIT pinout, MAX1833EVKIT application, or MAX1833EVKIT equivalent, this page provides verified board-level specifications, supported IC variants (MAX1832–MAX1835), output voltage configuration guidance, and supply-chain readiness for prototyping and design validation.

Technical Context

The MAX1833EVKIT implements a fixed-output 3.3V boost converter topology using the MAX1833EUT in 6-pin SOT23, with integrated synchronous rectifier PFET and RST output. Input range is 1.5V to VOUT (3.3V), enabling operation directly from single-cell alkaline or NiMH batteries.

It supports reconfiguration for adjustable outputs (2V–5.5V) by substituting MAX1832/MAX1834 and populating external feedback resistors R1/R2. Jumper JU1 selects between normal operation (pins 1–2 shunted) and shutdown mode (pins 2–3 connected to GND), reducing quiescent current below 1µA.

FAQ

What is the primary function of the MAX1833EVKIT?

The MAX1833EVKIT is a fully assembled evaluation board designed to validate the performance of the MAX1833 step-up DC-DC converter. It demonstrates 3.3V output generation from 1.5V–3.3V inputs at up to 150mA, with synchronous rectification and reverse-battery protection. Engineers use the MAX1833EVKIT to verify efficiency, transient response, and shutdown behavior before integrating the MAX1833 into final designs.

Can the MAX1833EVKIT evaluate other ICs besides the MAX1833?

Yes, the MAX1833EVKIT is explicitly designed to evaluate the full MAX1832–MAX1835 family. By replacing the onboard MAX1833EUT with MAX1832 or MAX1834 and configuring R1/R2 feedback resistors, users can test adjustable outputs from 2V to 5.5V. The MAX1835EUT may also be substituted for 3.3V operation with modified input headroom (VBATT − 0.7V).

How do I configure the MAX1833EVKIT for shutdown mode?

Configure shutdown mode on the MAX1833EVKIT by moving the shunt from JU1 pins 1–2 to pins 2–3. This connects the SHDN pin to GND, disabling the converter and reducing quiescent current to under 1µA. In shutdown, the output connects to VBATT through the inductor and internal PFET - a feature confirmed in the MAX1833EVKIT schematic and functional description.

What output voltage options does the MAX1833EVKIT support?

The MAX1833EVKIT defaults to 3.3V output using the MAX1833EUT. With hardware changes - IC substitution (MAX1832/MAX1834) and resistor selection (R1/R2) - it supports 2V–5.5V outputs. The feedback equation R1 = R2 × ((VOUT / 1.228V) − 1) applies, with R2 recommended between 100kΩ and 1MΩ per the MAX1832–MAX1835 data sheet referenced in the MAX1833EVKIT documentation.

Is the MAX1833EVKIT RoHS-compliant and lead-free?

Yes, the MAX1833EVKIT uses RoHS-compliant, lead-free surface-mount components including Taiyo Yuden and TDK ceramic capacitors, Sumida inductors, and standard 0805/1206 resistors. The MAX1833EUT IC itself is offered in lead-free 6-pin SOT23 packaging, consistent with Maxim's product compliance documentation dated 2001 and later revisions.
